Answer:
yes
Step-by-step explanation:
The triangle inequality requires the sum of the two short sides exceed the long side.
6 +14 = 20 > 18
The triangle inequality is satisfied by these numbers, so they could be the side lengths of a triangle.

Answer:
B = 47°
Step-by-step explanation:
THe theorem to solve this is very simple. The angle created Angle B intercepts to arcs, one major, another minor.
The major arc is DE, 142 degrees.
The minor arc is AC, 48 degrees.
The two secants intersect outside the circle and creates a vertex angle, Angle B. The theorem tells us that the measure of that vertex angle would be ONE HALF of the difference of the two intercepted arcs. So, we have:
So, B = 47°
